Definitions

  • the invention relates to a valve upper part, in particular for sanitary fittings, with a sleeve-like head piece which can be fastened in a valve housing of a fitting and which is centrally penetrated by a spindle which has a handle connection and is rotatably mounted about its longitudinal axis and via which a valve body can be actuated, according to the preamble of Claim 1.
  • Valve tops of the aforementioned type are, for example from the DE 32 07 895 , of the DE 33 23 008 as well as the US 2016/084403 A1 known.
  • the known problems arise with the known valve upper parts. There is a slight radial play between the spindle and the head piece, which is transmitted via the handle connection to the operating handle mounted on it, the impression of considerable play being conveyed due to the lever of the handle. Furthermore, in the case of fittings mounted horizontally on a wall, in which a heavy, asymmetrically designed operating handle is mounted on the valve upper part, the torque exerted on the spindle of the valve upper part can result in the handle automatically opening from a radially upper part when the valve is open Position pivoted into a radially lower position.
  • the invention seeks to remedy this.
  • the invention has for its object to provide a valve upper part in the game between the spindle and head piece and unwanted pivoting movements between the spindle and head piece are avoided, which is easy to manufacture even with small dimensions of the valve upper part and in which a constant feel even over a long period is guaranteed.
  • this object is achieved by an upper valve part with the features of the characterizing part of patent claim 1.
  • a valve upper part is created in which both play between the spindle and head piece in the radial direction and unwanted pivoting movements of the spindle in the head piece are avoided, which is easy to manufacture even with small dimensions of the valve upper part and which also remains constant over a longer period of time Haptic guaranteed. Due to the fact that a groove is made in the spindle, which receives an elastic sliding bush which at least partially radially encompasses the spindle and which at least partially abuts the inner circumferential surface of the head piece, the prior art requires the complex introduction of an axial recess into the head piece no longer required to accommodate the elastic plastic bearing. All that is needed is another groove in the spindle to accommodate the sliding sleeve.
  • the elastic sliding sleeve arranged in the groove is arranged completely elastically between the spindle and the head piece, so that irreversible, plastic deformations, as can occur in the pressed-in plastic bearing according to the prior art, are avoided.
  • the sliding bushing is preferably made of plastic, preferably of an elastomer.
  • the sliding bush is curved in such a way that it lies only in some areas both on the base of the groove and on the inner lateral surface of the head piece. As a result, the elastic behavior of the sliding bush is further improved, whereby plastic deformations are further avoided. This ensures a constant haptic of the valve upper part over a very long period of time.
  • the sliding bush is slotted. This enables simple mounting of the sliding bushes.
  • the sliding bush can be clipped onto the groove base of the groove. This enables simple, automated assembly of the slide bush. In addition, the use of sliding bushes made of different materials for different purposes can be easily implemented within a production process.
  • the slot of the sliding bush is V-shaped. This enables the slide bush to be simply clipped onto the groove base of the spindle, which further simplifies assembly.
  • the sliding bush rests on the groove base with a radially circumferential first contact surface and on the inner circumferential surface of the head piece with at least one, preferably two outer, radially circumferential second contact surfaces which are arranged axially offset from the at least one first contact surface.
  • the sliding bush can also bear against the inner circumferential surface of the head piece with an outer radially circumferential second contact surface and against the bottom of the groove with two circumferential first contact surface which are arranged axially offset from the second contact surface.
  • a nested arrangement of a plurality of contact surfaces lying against the groove base of the spindle and on the inner lateral surface of the head piece is also possible.
  • the valve upper part selected as an exclusion example has a head piece 1 which is penetrated in the center by a spindle 2 which is guided radially in it.
  • a control disk 3 is positively connected to the spindle 2 and guided radially in the head piece 1.
  • an inlet disk 4 is provided in the head piece 1, which is followed by a lip seal 5 which comes into contact with the valve seat of a valve (not shown).
  • the head piece 1 is formed from a symmetrical hollow body, the two end faces of which are open. On its side facing the fitting (not shown), the head piece 1 has a sleeve-shaped part 14. In the sleeve-shaped part 14, passage windows 11 are provided, which are delimited by longitudinal webs 12. In the exemplary embodiment, two windows 11 delimited by longitudinal webs 12 are arranged. After inserting the head piece 1 into a fitting, a collar 13 of the head piece 1 rests on the housing of the fitting. The collar 13 has on its side facing the passage window 11 an annular groove 15 for receiving an O-ring 151. In the sleeve-shaped part 14, a backward rotation 16 is arranged on the inside in the region of the end facing the valve seat. At its end opposite to the passage window 11, an external thread 17 is formed on the head piece 1, to which an external hexagon 18 connects for the engagement of a screwing tool.
  • the spindle 2 is essentially solid. It is provided on its end facing away from the water inlet with a handle connection 21, which is designed on the outside as an external polygon 211 and is provided with a blind hole 212 with an internal thread for fastening a twist grip (not shown).
  • the handle connection 21 is followed by a cylindrical section 22, with which the spindle 2 is guided radially in the head piece 1 and in which two ring grooves 24 are introduced for receiving O-rings 241, which seal the spindle 2 against the head piece 1.
  • a further annular groove 25 for receiving a sliding bush 6 is arranged between the annular grooves 24 receiving an O-ring 241 in each case.
  • a recess 23 is also provided, in which a shaft lock 231 in the form of a snap ring is resiliently inserted.
  • a cantilever 27 is formed axially on the cylindrical section 26, which essentially has a T-shaped cross section and which projects on one side beyond the diameter of the cylindrical section 25.
  • a protrusion 271 is formed on the side walls of the bracket 27 by the T-shaped cross section.
  • the cantilever 27 is designed such that it bears at two defined pivot positions on a stop surface 191 of a stop 19 formed on the inner wall of the head piece 1 with a side surface, the projection 271 arranged on this side surface projecting beyond the stop 19 with a small axial distance.
  • a disk 28 is formed on the extension arm 27 and has a driver 281 on its side facing the valve (not shown). With its top opposite the driver 281, the disk 28 bears against the underside of the disk 19, which is designed in the form of an arcuate web, of the head piece 1.
  • the control disk 3 is essentially designed as a circular disk, from which a circular section is excluded. In the exemplary embodiment, the circular section has an angle of approximately 180 °. On its upper side facing the spindle 2, the control disk 3 is also provided with a receptacle for the driver 281 of the spindle 2.
  • a lip seal 5 Adjacent to the inlet disk 4, a lip seal 5 is introduced into the head piece 1, which lip is provided all around with a web 51 which engages in the backward rotation 16 provided for this purpose in the sleeve-shaped part 14 of the head piece 1.
  • the lip seal 5 is held in position by an inserted support ring 52, the lips of the lip seal 5 sealingly abutting the inlet disk 4 and the valve seat (not shown).
  • the sliding bush 6 is designed as an annular plastic body which is separated on one side by a V-shaped slot 61.
  • the inner lateral surface of the sliding bush 6 is essentially convex and has a centrally arranged, circumferential first contact surface 62. Opposite the first contact surface 62, the outer lateral surface of the sliding bush 6 has a concave curvature 63, as a result of which two circumferential second contact surfaces 64 arranged parallel to one another are delimited.
  • the sliding bush 6 rests with the first contact surface 62 on the groove base of the annular groove 25 of the spindle 2, wherein it rests on the inner lateral surface of the head piece 1 with its second contact surfaces 64 arranged offset to the first contact surface.
  • the sliding bush 6 can also have a central second contact surface on its outer lateral surface and two first contact surfaces running parallel to one another and offset from the inner second contact surface.) In this way, there is an elastic and completely reversible sliding bush 6 between the spindle 2 and the head piece 1 achieved. Through the V-shaped slot 61, the sliding bush 6 can be simply clipped onto the annular groove 25 of the spindle 2.
  • Headpiece and spindle of an upper valve part are shown in a further embodiment, in which the control disk has a circular cutout of approximately 90 ° and a maximum angle of rotation of the spindle of 90 ° is set up.
  • the arm 27 ′ which in turn has a T-shaped cross section, as a result of which a projection 271 ′ is formed on each of its two side surfaces, in such a way that the one on two diametrically opposite sides has the diameter of the cylindrical section 25 the spindle 2 'protrudes.
  • two stops 19 'designed as arcs in the form of a circular arc are arranged opposite one another within the head piece 1, on the stop surfaces 191' of which one side surface of the bracket 27 'abuts in one stop position of the spindle 2'.
